For example modulation bandwidths in excess of 50MHz are readily achievable. In an AOM a laser beam is caused to interact with a high frequency ultrasonic sound wave inside an optically polished block of crystal or glass (the interaction medium). By carefully orientating the laser with respect to the sound waves the beam can be made to reflect off the acoustic wavefronts (Bragg diffraction). Therefore, when the sound field is present the beam is deflected and when it is absent the beam passes through undeviated. By switching the sound field on and off very rapidly the deflected beam appears and disappears in response (digital modulation). By varying the amplitude of the acoustic waves the intensity of the deflected beam can similarly be modulated (analogue modulation). It is usual to choose the deflected beam as the one that is used in the optical system because it can be switched on and off with high extinction ratio (typically >40dB) and intensity can be varied from zero to more that 85% of the incident beam. The rate at which the beam can be modulated is governed by the time it takes the acoustic wavefronts to traverse the laser beam, which depends on the beam diameter and the acoustic velocity in the interaction medium. The sound waves are generated by a transducer, usually a thin wafer of lithium niobate, that is bonded onto the interaction medium using a highly efficient cold-weld metallic bonding process. When a high frequency electrical signal is applied to the transducer it vibrates, generating the acoustic wave. The signal is derived from an RF driver, which generates a high frequency carrier that is itself modulated by an analogue or digital input signal. AO Modulator Cell Schematic Fiber-coupled AO Modulator Cell Schematic Principal applications for AO modulators are pre-press (putting image and text data onto films or plates as part of the printing process), laser imaging and displays, switching in telecom fibres, instrumentation and research.

2 Sintec Optronics Technology Pte Ltd 1. Free-space Acousto-optical Modulators We offer a wide range of standard AO Modulators, for digital or analogue intensity modulation of laser beams. Their main specifications are as follows: Wavelength Range: 240nm to 2100nm Drive Frequencies: 20MHz to 350MHz Optical Rise-Times: Down to 5ns Modulation Bandwidths: Up to 100MHz Interaction Materials: Tellurium Dioxide, Lead Molybdate, Fused Silica, Crystal Quartz, halcogenide Glass, Flint Glass. An RF Driver provides the electronic signal operating the AO Modulator. With a digital driver, an external TTL signal enables rapid on and off switching of the optical beam. Alternatively an anologue driver enables a variable intensity output, typically from 0% to 85% of the input beam. The maximum modulation bandwidth, or optical rise-time, is a function of the acoustic transit time across the optical beam. Therefore, for the highest speeds it is often necessary to focus the optical beam down to a small spot inside the modulator. Our standard AOMs are listed below.

17 AOM Driver: A35xxx (40 to 350MHz, 5W) The A35xxx RF driver series provides up to 5 Watt output power. Various types cover a frequency range from 80 to 350 MHz. The frequency is customizable. The maximum RF output power is adjustable by an internal potentiometer. The analogue modulation voltage controls the output power from 0 to 100% of the adjusted maximum power. Additional to the analogue modulation voltage a digital modulation control signal can switch on and off the RF power. An operation scheme below illustrates the interaction of the two modulation signals in detail Both the analogue and digital modulation are characterized by extraordinary on/off ratios of at least 65dB. The driver can be operated with modulation frequencies (analogue and digital) up to 1/4 of the carrier frequency. Optimum EMC shielding and mechanical protection is achieved by an aluminium casing and a conductive surface passivation. The base plate serves for mounting as well as for heat dissipation. Also a compatible base plate style, which eases maintenance of facilities equipped with legacy drivers A33x or A34x, is available. Key Features: Frequency range 80 to 350 MHz RF output power 5 Watt Optimized for grey-scale applications RF on/off ratio > 65 db Constant output power design: maximum fluctuation ± 5% between cold and warm state Modulation frequency up to 50 MHz Conductive cooling through base plate Compact housing, fully shielded (EMC) Applications: Fast modulation components for extra cavity applications, e. g. laser projection systems Frequency shifting Technical Data Supply voltage +24 VDC Supply current typ W RF output power Output impedance nom. 50Ω Maximum RF output power (adjustable) * > 5 W (+37 dbm) Analogue modulation Impedance 50 or 600Ω Voltage 50Ω 0 +1 V or 0 +5 V ** Voltage 600Ω 0 +5 V or V ** RF ON / OFF ratio > 65 db Digital modulation Impedance 4k7 or 50 _ (pull-up or pull-down) ** Level High = 3V 5V Low = 0 < 2V Logic styles Input signal: High Low not connected positive logic, pull-up RF power: on off on positive logic, pull-down on off off negative logic, pull-up off on off negative logic, pull-down off on on RF ON / OFF ratio > 100 db * into 50Ω load ** other combinations on request Tel:
